BRICK-MAG H'l N E.

SPECIFICATION forming part of Letters Patent No. 237,729, dated FebruaryI5, 1881, I Application filed November 19, 1880. (No model.)

To all whom 'it may concern:

Be it known that we, ISRAEL OULLEN, JAMES C. OONROY, and HENRY D.KILGORE, all of the city of Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented new and useful Improvements inBrick-Machines; and we do hereby declare that the following is a full,clear, and exact de-.

pered clay down into two receivers, where two plun gers, moving at rightangle to the vertical axis of said receivers, force the clay from theminto brick-molds held in position with relation to the discharge of saidreceivers until they are filled with clay under pressure, after whichthey are relieved from the holding device for the purpose of allowingthe clay pressed into said molds to expand priorto the operation ofcutting the clay for separating the molds and the brick in them from theclay in the receivers, said mill, plungers, receivers, molds, andholding and separating mechanism operating with relation to each otheras will herelnafter more fully appear.

To enable others skilled in the art with which our invention is mostnearly connected to make and use it, we will proceed to describe morefully its construction and operation.

In the accompanying drawings, which form part of our specification,Figure l is a side elevation of our improvement in brick-machines,representing the side of the clay-mill broken away for purpose ofshowing the interior of said clay-milk Fig. 2 is a front elevation ofour improvement. Figs. 3, 4:, -5, 6, 7, and 8 are Figs. 9 and 10 arevertical sections through line y y of Fig. 1 when viewed from oppositesides thereof.

In the accompanying drawings, A represents the frame of the machine, andB the mill for tempering the clay. In the bottom of this mill are twoapertures, s 8, through which the tempered clay is forced by two'vertical-moving p'lungers, e 0, into two receivers, u u, for chargingthe brick-molds 7a with clay, which is forced from said receivers intosaid molds by means of two plungers, r r, which move horizontally insaid receivers, with an alternate and reciprocating action imparted tothem by the friction-roller t of the disk n on shaft 0.Thefriction-rollertmoves in a yoke formed by bars 0 c and cross-bars1 1. Said bars 0 c are attached to the plungers r r, which movehorizontally in receivers 10 a, that serve as guides for said plungers rr and bars 0 c, as represented by dotted lines, Fig. 1, and a top viewof said parts,Fig. 4. The friction-roller t, coming alternately againstthe cross-barsl 1, imparts to the bars 0 c, to which the plungers r rare attached, a reciprocating motion.

The bars 0 0' may be constructed as indicated in Fig. 8, for the purposeof varying the dis- .tancebetween the cross-bars 1 1, thereby regulatingthe distance of travel of the plungers r r, and thereby secure thedesired pressure of clay in the brick-molds. The bars 1 1 (see Fig. 4)are cut away at 2 for the purpose of allowing the clay to expand in themolds and receivers after receiving the force of the plun gers. Thefriction-roller 25 coming opposite to this cut-away part of said bars,the plungersr 4 will move back by the expansive action of the clay inthe molds and receivers, which expansion should take place prior toseparating the mold and bricks therein from said receivers, which iscaused by the downward movement of the wire or knife .90, which is ofordinary construction, the arrangement of which will hereinafter morefully appear.

To the outer ends of the rocking arms h, at t, are pivoted slides f,which move in guides g, said rocking arms being pivoted to pendants d d,as shown in Fig. 10; I

To the slidesfare attached plun gerse, which, in their downwardmovement, force the tempered clay through the apertures 8 into thereceivers 41. y g p The rocking arms h receive their motion through themedium of the pendants 8, disk m, and friction-roller 0, moving theslide-bars j by coming in contact with the cross-bars 2, as indicated inFig. 3.

On the outer side of the slidebars j is a projecting pin, a, whichprojects through the slot in the pendants s of the rocking arms h. Hencethe motion imparted to the sliding bars j through the medium of pins ais transmitted to the rocking arms h.

The disk on is secured on the shaft 0, and receives its motion from saidshaft-that is, it revolves with said shaft.

On the under side of the disk in is a frictionroller, 1, which operatesthe sliding bars it,

having crossbars, (arranged in the same manner as the CFOSS-b1PS 2 2shown in Fig. 3,) against which the friction-rollers 1) act for thepurpose of imparting to the sliding bars 7; a reciprocating motion.

On the under side of the bars I; are pendants w, to which are pivotedconnectiops x, which are pivoted to arms you a shaft, a, having suitableheariu gs.

On the shaft a are secured rocking arms I), to the outer ends of whichis pivoted the frame to, which carries the wire or knife 00, which movesin a vertical plane with the frame w, which receives its motion throughthe medium of the rocking arms I).

The brick-molds It" are of the ordinary construetion when made forforming or molding three bricks at a single charge. The molds aresupported in front of the discharge-openings of the clay-receivers a bymeans of a stationary breast-plate, a, secured to the frame A. Thedischarge of the clay-receivers is divided by partitions t, havingbeveled sides, as shown in Fig. 7, said partitions corresponding inposition to the partitions y of the brick-molds 7t--that is to say, thepartitions of the receivers will he opposite to the partitions of thebrick-molds when said molds arein position for receiving clay from thereceivers u. The bottom a of the brick-mold is detached from the moldand is pivoted to an S-shaped arm on a shaft, 1/, the bearings of whichare secured to the frame A.

The rocking arms I) have a rod or shaft, 0, which extends from one tothe other, as shown in Fig. 2, and on this rod or shaft 0 is afriction-roller, d, which acts against the S-shaped arm I) for holdingthe bottom a firmly against the brick-mold k.

The construction and arrangement of the several parts of the machinewill be readily understood from the foregoing description and byreference to the accompanying drawings.

Y \Vewill therefore proceed to describe its operation.

1 Clay having been previously moistened with water, is charged into thetempering-mill B. The shaft C, being turned by means of the lever orsweep A, willrevolve the tempering-arms D and filling-arm D, which willthoroughly temper the clay. The filling-arm D will carry the temperedclay under the plungers c, which will force it down through apertures 5'into receivers u, and the disk, with its friction-roller t, causes theplungers a" to alternately force the clay from the receivers to into thebrick-molds k, the friction-roller d pressing against the lower part ofarm I), which will hold bottom a of the brick-mold k firmly against saidmold during the operation of the plunger 2", filling the mold, at whichpoint the downward movement of the rocking arms b wiil allow the bottoma of the mold It to move back slightly, and, the plunger 0' moving backslightly at the same time, the clay in the mold and receiveris allowedto expand the rocking arms I), moving downward the frame 10, whichcarries the wire or knife 00. The latter, passing between the mold andreceiver, separates the clay in the mold from the clay in the receiver.The mold is then removed and the brick discharged from it in the usualmanner. The mold is then sanded and replaced on the machine, ready to beagain filled.

Having thus described our improvement, what we claim as of our inventionis 1. Inabrick-machine, the combination of the tempering-mill furnishedwith two discharging-apertures and two interior vertical plungers movingvertically over said apertures, two receivers arranged under saiddischargeapertures, two plungers moving at right angles to the verticalaxis of said receivers for forcing the clay from said receivers into thebrickmolds, and means, substantially as described, whereby said moldsare held in position until filled with clay under pressure, andsubsequently relieved from pressure for the purpose of allowing the clayto expand in said molds prior to the operation of cutting the clay forseparating the molds and the brick in them from the clay in thereceivers, substantially as specified.

2. In a brick-machine, the combination of the plungers c 1', receiversin u, molds k, and breast-plate or holding device a, arranged andoperating with relation to each other substantially as herein described,and for the purpose set forth.

8. In a brick-machine, the combination of the shaft 0, disks m a,furnished with frictionrollers 01) t, sliding bars a j 70, rocking armsI) h, operating with relation to the molds 7:, arms I), receivers u u,and plungers e 1" substantially as herein described, and for the purposeset forth.
